John Alexander (26 July 1802 – October 1885)[1] [2] was an Irish Conservative politician.
Alexander was the son of his namesake, John Alexander, and Christian née Izod. In 1848, he married Esther Brinkley, daughter of Matthew Brinkley; the couple had six children: John Alexander (born 1850); William Cranstoun Alexander (born 1851); Lorenzo Alexander (1853–1942); Charles Henry Alexander (born 1856); George Alexander (1858–1930); and Harriet Lucia Alexander.[2]
After holding the office of High Sheriff of Carlow in 1824, Alexander was elected as the Conservative Member of Parliament (MP) for Carlow at a by-election in 1853, defeating John Sadleir who had been required to stand in a by-election after he was appointed a Lord Commissioner of the Treasury. He held the seat until his defeat at the 1859 general election.[2] [3]
